Answer:

"The square root of 12 is between 4 & 5."

Step-by-step explanation:

1. "The square root of 12 is between 4 & 5" This doesn't make sense: 4 squared is 16 and 5 squared is 25. 12 is not between either of those numbers.

2. "The square root of 90 is between 9 & 10." 9 squared is 81, 10 squared is 100. 90 is between those numbers, so this makes sense.

3. "The square root of 40 is between 6 & 7." 6 squared is 36, and 7 squared is 49. 40 is between these numbers, so that makes sense.

4. "The square root of 5 is between 2 & 3." 2 squared is 4, and 3 squared is 9. 5 is between those two numbers, so this makes sense.

Therefore, the statement that is not true is the first one: "The square root of 12 is between 4 & 5."

I hope this helps!

Find the surface area of the prism.

Maurinko [17]

Answer:

326m²

Step-by-step explanation:

Find the area of each side and find the total sum from each individual area:

2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326

So the surface area of the prism is 326m²

solniwko [45]

Answer:

$z_{stat} = -1.50$

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 108

Sample mean, $\bar{x}$ = 107

Sample size, n = 110

Alpha, α = 0.02

Population standard deviation, σ = 7

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{107 - 108}{\frac{7}{\sqrt{110}} } = -1.50$

The test statistic is -1.50

What is the area of this figure?

ludmilkaskok [199]

Answer:

$\large\boxed{\large\boxed{42 unit^2}}$

Explanation:

The figure is not a regular hexagon. It is an irregular hexagon.

Please, find attached the picture with the original question and the figure.

You can split the figure into two triangles and one rectangle.

The rectangle has dimensions: 7units × 4units, thus its area is 28 units².

Both the upper triangle and lower triangle have base 7 units and height 2 units.

Hence the area of each triangle is:

$area=(1/2)base\times height$

$area=(1/2)7units\times 2units = 7units^2$

Hence, the area of the hexagon is:

$28units^2+7units^2+7units^2=42units^2$
